What You'll Learn
Soy candles should cure for two weeks
Soy candles are made from "'vegetable waxes", which are polymorphic. This means that they continue to harden over their entire lifetime, as crystals form in the wax in response to time and temperature. This process begins as soon as the candle is poured, with the wax cooling and solidifying.
Because of this polymorphic hardening, soy candles need to cure for longer than candles made from other types of wax, such as paraffin candles. While candles made from paraffin wax reach almost full hardness within a day or two of pouring, soy candles continue to harden over time, with many in the candle-making community believing that most hardening occurs within the first 14 days after pouring.
Therefore, it is recommended that soy candles cure for at least two weeks before burning. This allows the wax to harden sufficiently, so that it requires the correct amount of heat to melt. Burning a candle too soon can yield false results, as more heat is required to melt harder wax.
Curing also allows the fragrance oil and wax to bind together and spread evenly before the wax sets. This process takes time, and the longer a soy candle is allowed to cure, the more scent it will release when burned. While a soy candle can be burned after just one week, it is best to wait for two weeks to get the strongest scent.

Curing impacts candle fragrance and performance
Secondly, curing affects the distribution of fragrance oils in the wax. Cooling wax traps fragrance oil molecules, which spread out as the wax hardens over time. Candle curing helps to disperse fragrance oils evenly throughout the blend. This process can vary depending on the wax and fragrance oil combinations, with some requiring more time to reach an optimal state. The curing process can impact the strength of the fragrance when the candle is burned, as well as when it is unlit (known as "cold throw" and "hot throw" in candle-making).
Thirdly, curing can help to prevent issues such as candle tunnelling, which can occur when the middle of the candle is softer than the outside due to insufficient curing. Allowing the candle to cure for longer can create a more consistent texture, improving the burn performance and ensuring the candle burns down evenly.
Finally, curing times can vary depending on the type of wax and fragrance used. For example, paraffin wax typically reaches almost full hardness within a day or two of pouring, while soy wax continues to harden over time due to its polymorphic nature. Heavier scents may also be ready to burn more quickly than lighter, more delicate fragrances. Therefore, curing times can impact the performance and fragrance of a candle, and it is important to consider these factors when creating and testing candles.

Candle safety: burning times and hazards
Candles are a great way to create a warm and tranquil atmosphere, but it's important to follow some basic safety guidelines to avoid potential hazards. Here are some tips for candle safety, focusing on burning times and hazards:
Burning Times
The burning time of a candle can vary depending on several factors, including the type of wax, the presence of fragrance oils, the type of wick, and the size of the candle.
- Paraffin wax candles have longer burn times compared to other wax types like beeswax or soy wax. Paraffin-based candles can burn for about 10 to 15 hours per inch of diameter.
- Beeswax candles have a pleasant honey-like scent and can typically burn for about 8 to 12 hours per inch of diameter.
- Scented candles, due to the presence of fragrance oils, tend to burn faster than unscented candles. Their burn time is usually around 7 to 10 hours per inch of diameter, depending on the specific fragrance and wax type.
- Cotton core wicks provide a steadier flame and longer burn times, while wooden wicks may produce more smoke and have shorter burn times.
- Larger candles generally take longer to burn than smaller ones, as there is more wax to melt.
Candle Care and Safety Hazards
To ensure the safe burning of candles and reduce potential hazards, follow these guidelines:
- Always trim the wick to about 1/4 inch before lighting the candle. This helps prevent candle tunneling and extends the life of the candle.
- Limit each candle to a burn time of 2 hours, and absolutely no more than 4 hours at a time. Longer burn times can create potential fire hazards, especially if the candle is left unattended.
- Always manually extinguish the candle. Do not rely on it burning down to the bottom, as this can be dangerous.
- Allow the candle and its container to cool completely before relighting it.
- Never leave a burning candle unattended. Keep it away from flammable materials, drafts, and pets.
- Consider using flameless LED candles as a safer alternative.
- Proper candle care is crucial. Trim the wicks regularly and follow the manufacturer's instructions for recommended burn times and safety guidelines.
- When extinguishing the flame, check that there are no remaining embers or glowing parts on the wick.
- Discard the candle when only half an inch of wax remains. Burning it beyond this point can overheat the bottom and create a safety hazard.
- To speed up the cooling process, you can use the water bath method or place the candle in the refrigerator after hardening it at room temperature.

How to speed up candle cooling
The cooling time of a candle depends on the type of wax used. For example, paraffin waxes reach almost full hardness within a day or two of pouring, whereas soy waxes continue to harden throughout their life. In general, the candle-making community believes that the most hardening occurs within the first 14 days after pouring.
To speed up the cooling process, you can try the following methods:
Use a Water Bath
Fill a container with cool water—the ideal temperature is between 15° Celsius (59° Fahrenheit) and room temperature. Pour your candle, tap it to remove air bubbles, and then place it in the water bath. Weigh it down so that the mould stays steady, and fill the container with more cool water. Leave the candle to set for 30 minutes to an hour, depending on the size of the mould and the weight of the candle.
Refrigerate the Candle
Once your candle is no longer liquid and is lukewarm, you can place it in the refrigerator to speed up the cooling process. Metal moulds can be refrigerated for an hour, while plastic or polycarbonate moulds may only need 20 minutes.
It is important to note that candles should not be placed in the freezer, as this may cause the wax to crack.
By following these methods, you can significantly reduce the time it takes for your candles to cool and harden.
